When using two-terminal bi-color LEDs, the mixing
percentage should not be set greater than 50%.
0000b = 0%.
0001b = 12.5%.
0111b = 87.5%.
1000b = 100%.
1001b - 1111b = Reserved.
After a hardware reset, this bit is a function of
pd_config_led_a[1:0].
00b = 0100b.
01b = 0100b.
10b = 1000b.
11b = 1000b.
